=head1 NAME

perlhist - the Perl history records

=head1 DESCRIPTION

This document aims to record the Perl source code releases.

=head1 INTRODUCTION

Perl history in brief, by Larry Wall:

   Perl 0 introduced Perl to my officemates.
   Perl 1 introduced Perl to the world, and changed /\(...\|...\)/ to
       /(...|...)/.  \(Dan Faigin still hasn't forgiven me. :-\)
   Perl 2 introduced Henry Spencer's regular expression package.
   Perl 3 introduced the ability to handle binary data (embedded nulls).
   Perl 4 introduced the first Camel book.  Really.  We mostly just
       switched version numbers so the book could refer to 4.000.
   Perl 5 introduced everything else, including the ability to
       introduce everything else.

=head2 PUMPKIN?

[from Porting/pumpkin.pod in the Perl source code distribution]

=for disclaimer orking cows is hazardous, and not legal in all jurisdictions

Chip Salzenberg gets credit for that, with a nod to his cow orker,
David Croy.  We had passed around various names (baton, token, hot
potato) but none caught on.  Then, Chip asked:

[begin quote]

   Who has the patch pumpkin?

To explain:  David Croy once told me that at a previous job,
there was one tape drive and multiple systems that used it for backups.
But instead of some high-tech exclusion software, they used a low-tech
method to prevent multiple simultaneous backups: a stuffed pumpkin.
No one was allowed to make backups unless they had the "backup pumpkin".

[end quote]

The name has stuck.  The holder of the pumpkin is sometimes called
the pumpking (keeping the source afloat?) or the pumpkineer (pulling
the strings?).

The "core"..."doc" mean the following files from the Perl source code
distribution.  The glob notation ** means recursively, (.) means
regular files.

 core   *.[hcy]
 lib    lib/**/*.p[ml]
 ext    ext/**/*.{[hcyt],xs,pm} (for -5.10.1) or
        {dist,ext,cpan}/**/*.{[hcyt],xs,pm} (for 5.12.0-)
 t      t/**/*(.) (for 1-5.005_56) or **/*.t (for 5.6.0-5.7.3)
 doc    {README*,INSTALL,*[_.]man{,.?},pod/**/*.pod}

Here are some statistics for the other subdirectories and one file in
the Perl source distribution for somewhat more selected releases.

=head2 SELECTED PATCH SIZES

The "diff lines kB" means that for example the patch 5.003_08, to be
applied on top of the 5.003_07 (or whatever was before the 5.003_08)
added lines for 110 kilobytes, it removed lines for 19 kilobytes, and
changed lines for 424 kilobytes.  Just the lines themselves are
counted, not their context.  The "+ - !" become from the diff(1)
context diff output format.

=head3 The patch-free era

In more modern times, named releases don't come as often, and as progress
can be followed (nearly) instantly (with rsync, and since late 2008, git)
patches between versions are no longer provided. However, that doesn't
keep us from calculating how large a patch could have been. Which is
shown in the table below. Unless noted otherwise, the size mentioned is
the patch to bring version x.y.z to x.y.z+1.
